[0028] The working principle of the utility model is as follows:

[0029] During the vertical drilling and tapping process, the staff places the workpiece with arc surface side wall to be drilled and tapped on the upper surface of the top plate 16, and then starts the motor 2 19 by adjusting the control switch group 22. The output shaft of the motor 2 19 rotates to drive the screw rod 18 to rotate. The screw rod 18 rotates to drive the sliding support seat 9 to move to the left under the limiting effect of the guide rail 8, so that the workpiece with arc surface side wall to be drilled and tapped is located below the drilling cutter 20. Then the external air compressor is controlled to supply air to the cylinder 15. The air intake of the cylinder 15 causes the telescopic end to move upward. The telescopic end of the cylinder 15 drives the top plate 16 upward, and the top plate 16 drives the workpiece with arc surface side wall upward.

[0030] Then the staff rotates the handle 14, and the rotation of the handle 14 drives the fixed support column 138 to rotate. The rotation of the fixed support column 138 drives the connecting top plate 139 and the rotating frame 136 to rotate at the same time, thereby driving the rotating connecting frame 137 to rotate. The rotating connecting frame 137 rotates so that the clamping frame 135 rotates with the connection with the sliding mouth 134 as the center of the circle. The clamping frame 135 rotates and slides inside the sliding mouth 134. The proximal end of the clamping frame 135 is close to the center of the connecting top plate 139, so that the clamping frame 135 clamps the wall surface of the workpiece with a circular arc side wall, thereby clamping workpieces of various sizes and increasing the contact points with the workpiece, so as to clamp the workpiece with a circular arc side wall, so as to avoid the workpiece shaking during the processing and affecting the drilling and tapping accuracy;

[0031] Then, the external air compressor is controlled to stop supplying air to the pneumatic push rod 6 on the right side. Under the action of the external air pressure, the telescopic end of the pneumatic push rod 6 on the right side moves downward, so that the support plate 5 on the right side moves downward, and the support plate 5 moves downward to drive the sliding mounting seat 4 to move downward, and the sliding mounting seat 4 moves downward to drive the motor 7 to move downward. At the same time, the staff starts the operation of the motor 7 on the right side by adjusting the control switch group 22. The operation of the motor 7 drives the drilling cutter 20 to rotate, and the drilling cutter 20 rotates and contacts the workpiece with the arc side wall, thereby completing the vertical drilling;

[0032] After the drilling is completed, the pneumatic push rod 6 on the right side is supplied with air through the external air compressor to reset the drilling cutter 20, and then the motor 2 19 is started by adjusting the control switch group 22. The operation of the motor 2 19 drives the screw rod 18, and the rotation of the screw rod 18 causes the sliding support seat 9 to continue to move to the left under the limiting action of the guide rail 8, and then the air supply to the pneumatic push rod 6 on the left side is stopped through the external air compressor, and the telescopic end of the pneumatic push rod 6 moves downward, so that the support plate 5 on the left side moves downward, and the downward movement of the support plate 5 drives the sliding mounting seat 4 to move downward, and the downward movement of the sliding mounting seat 4 drives the motor 1 7 to move downward. At the same time, the staff starts the operation of the motor 1 7 on the left side through the adjustment of the control switch group 22, and the motor 1 7 drives the tap 21 to rotate, and the rotating tap 21 contacts the drilled hole on the workpiece with the arc surface side wall, thereby completing the tapping of the drilled hole, thereby completing the vertical drilling and tapping of the workpiece with the arc surface side wall.

[0033] It is worth noting that the motor 1 7 disclosed in the above embodiment can be selected as YDT80-2 80W, and the motor 2 19 can be selected as YS-5624. The control switch group 22 is provided with control buttons corresponding to the motor 1 7 and the motor 2 19 and used to control their switches.
